Dataset Name: River Change Dataset Dataset Source: http://umnlcc.cs.umn.edu/RiverChangeDataset/info.html Sample File URL: http://umnlcc.cs.umn.edu/RiverChangeDataset/box-224-sec-3.csv

Variables

For variables that need to be linked to SVO, please provide variable's name (as it appears in the data file), its description, and its type (categorical or numerical).

1. Time:
   • description: time of satellite imagery acquisition used for estimating river width and depth
   • type: categorical and string
2. River_Width:
   • description: measures the width (in meters) of the river along a cross section
   • type: numerical
3. River_Depth:
   • description: measures the depth (in meters) of the river along a cross section
   • type: numerical

@ankushkhandelwal Here are the variable names for your dataset. I provided some explanations as well as possible clarifications below:

1. Time:
   • description: time of satellite imagery acquisition used for estimating river width and depth
   • type: categorical and string
   • SVO label: event__observation_time
   • SVO URI: http://www.geoscienceontology.org/svo/svl/variable#observer%40role%7Esink_phenomenon%40role%7Emain_observation__observation_time
2. River_Width:
   • description: measures the width (in meters) of the river along a cross section
   • type: numerical
   • SVO label: channel~river_water_x-section__width
   • SVO URI: http://www.geoscienceontology.org/svo/svl/variable#channel%7Eriver%40context%7Ein_%28water_x-section%29__height
3. River_Depth:
   • description: measures the depth (in meters) of the river along a cross section
   • type: numerical
   • SVO label: channel~river_water_x-section__depth
   • SVO URI: http://www.geoscienceontology.org/svo/svl/variable#channel%7Eriver%40context%7Ein_%28water_x-section%29__width

Explanation:

1. event__observation_time this is the universal time for the dataset and all observation "events" recorded in the dataset
2. and 3. Channel is the general term used to describe the desired landform, and river is the type of channel (~ denotes taxonomic relationship). Depth and width are both types of "length".
   • Unless the cross section is assumed to be rectangular, it may be helpful to specify which depth and which width e.g., channel~river_water_x-section_top__width, URI: http://www.geoscienceontology.org/svo/svl/variable#channel%7Eriver%40context%7Ein_%28water_x-section_top%29__width channel~river_water_x-section__max_of_depth, URI: http://www.geoscienceontology.org/svo/svl/variable#channel%7Eriver%40context%7Ein_%28water_x-section%29__max_of_depth
   • If it is assumed to be rectangular, you may want to specify it like this: channel~river_water_x-section_rectangle__width

Hey! Could you also please provide the uri for these variables

[mariutzica]

Hi @ankushkhandelwal , the variables were not already in the ontology, so I temporarily generated their IRIs and included the URIs above. If you agree with these labels, I will go ahead and add them to the official SVO.

[ankushkhandelwal]

Hi @mariutzica Please add these two variables - "channel\~river_water_x-section_topwidth" "channel~river_water_x-sectionmax_of_depth"

I am assuming the uris will change as well because the ones that we have right now don't incorporate top and max keywords in them.

@ankushkhandelwal I just added the URIs to the previous post. I will add them to SVO as well. There may be a delay before they are up on the SPARQL endpoint, but you should be able to register them in the data catalog at any time.
